Python really doesn't try to avoid the concept of an End-of-file marker.

================
$ python3
Python 3.2.3 (default, Jun  8 2012, 05:36:09)
[GCC 4.7.0 20120507 (Red Hat 4.7.0-5)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> quit
Use quit() or Ctrl-D (i.e. EOF) to exit
>>> import io
>>> print(io.FileIO.read.__doc__)
read(size: int) -> bytes.  read at most size bytes, returned as bytes.

Only makes one system call, so less data may be returned than requested
In non-blocking mode, returns None if no data is available.
On end-of-file, returns ''.
================

Cheers,
Nick.
